included.
·Kraus recommends providing the cabinet maker with the actual sink to
be installed prior to the cabinet fabrication.
·It is recommended that the sink be installed with an approximately 1/8"
positive reveal. It is further recommended that the installer(s) discuss this
with the customer and agree that this finished appearance is the desired
effect.

Installer Tip: Use acetone or denatured alcohol to remove any excess sealant.
5. Install Countertop
·Use a bead of silicone (or preferred adhesive) around the rim of the sink.
Check the alignment of the sink to the cutout in the countertop. Place
countertop cutout hole over sink and press firmly.
